Brief Summary

Intracranial artery stenosis is an important cause of ischemic stroke, but the degree of intracranial artery stenosis is not completely matched with the symptoms of ischemic stroke. Asymptomatic carotid stenosis (ACS) refers to does not appear related neurological symptoms of carotid stenosis and stroke or transient ischemic attack of carotid stenosis, did not happen cerebrovascular events such as stroke, but there have been a different degree of cognitive impairment, be badly in need of development of noninvasive imaging methods, objective evaluation of the ACS group cognitive impairment, and predict the ACS risk of ischemic stroke. Therefore, this topic proposed comprehensive cognitive assessment, CTA, double modal MRI techniques, clinical and biochemical indicator detection, mathematical modeling and statistical analysis techniques, assess the ACS group and normal person the cognitive ability, the difference of NVC and local perfusion, and follow-up ACS crowd of ischemic stroke and other cardiovascular events, discuss ACS and cognitive impairment, the correlation of NVC and local perfusion abnormalities, screening of radiographic predictor of ischemic stroke, and in the follow-up of ACS population in testing the sensitivity of the series of indicators and specific degrees.

No related neurological symptoms and transient ischemic attack	GE Discovery MR750 3.0t superconducting MRI	Mild stenosis group: CTA suggested carotid stenosis \< 30%; Moderate stenosis group: CTA suggested carotid stenosis of 30-69%; Severe stenosis group: CTA indicated carotid stenosis ≥70%;

Primary Outcome Measures

Name	Time	Method
Dynamic change and correlation analysis of multi-dimensional features of ACS degree and cognitive impairment	2020.01	The Montreal cognitive assessment (MoCA) scale was used to evaluate the differences in cognitive function between ACS and the healthy control group in different dimensions, and the horizontal correlation analysis between ACS and cognitive impairment was conducted according to the dimensions of cognitive impairment and the degree of ACS.
